Substructural Components

Our substructural components—including hat channels, U-channels, sub-girts, and related framing members—are engineered to provide a precise, reliable support system for metal roofing, wall panel, and façade assemblies. Manufactured for dimensional consistency and structural performance, these components ensure proper load transfer, alignment, and attachment across a wide range of architectural and commercial applications. Available in multiple gauges, profiles, and lengths, MPG substructural components integrate seamlessly with both standard and custom panel systems, supporting efficient installation, long-term durability, and code-compliant building envelope performanceC purlins and z purlins are part of the secondary framing structure. They’re designed to distribute loads from the surfaces of your metal building to its primary framing and foundation. This adds longitudinal support and provides lateral bracing for compression flanges, increasing the overall frame capacity.
